For Natalie Stewart, a
normal life has never seemed so far away. Her only solace, Lord Jonathan
Denbury, is wanted for murder. To clear his name, Denbury must return
to England and assume the role of his demon doppelganger. But Natalie
begins to doubt his true motives, especially as a new gentleman begins
whispering in her ear. Natalie and Denbury may be able to visit each
other in their dreams, but they can't escape the darkening shadows. Amid
spontaneous explosions, friends turned enemies and dangerous secrets
revealed, there's still a demon who has Natalie's scent, and someone is
trying to resurrect the ultimate evil.

I haven't read the first book in the series yet, "Darker Still",but the sequel sounds so unique! Sourcebooks Fire always does a great job with publishing unique types of stories, so I'm looking forward to this one!
